I love how Murphy and Lewis look completely different to their film actors, but in the brief half-a-second he appears, Boddicker is clearly Kurtwood Smith.

Usually a rights thing, maybe Kurtwood Smith signed off on them being allowed to use his likeness without him getting paid. Though, to me, it's not an "exact match" just very similar.

Yeah, it isn't, more than likely Smith didn't sign anything for a brief second in an opening intro (unless there was a specific thing in his Robocop contract saying his likeness could be used in spin-offs), but it is funny that while their Murphy and Lewis almost look like they're deliberately avoiding the actors' appearance, the Guy Who Kills Murphy is pretty obviously based on the Guy Who Kills Murphy in the film.
